We're dividing 312686 by 19 
Our goal is to divide 312686 by 19.

Step 1:
3 divided by 19 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 19

Advancing to step 2:
19 goes into 31 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 19 from 31 leaves us with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 19

Moving on to step 3:
122 divided by 19 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 8 after subtracting 114 from 122.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 19

Going ahead to step 4:
When dividing 86 by 19, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we take 76 away from 86, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 19

Going ahead to step 5:
108 divided by 19 is 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 1645.0
Deduct 95 from 108 and we're left with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 19

Moving on to step 6:
If we divide 136 by 19, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 16457.0
The remainder is 3 after subtracting 133 from 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 16457.1
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
19 can be fit into 110 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 16457.15
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 16457.157
Deduct 133 from 150 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
19 goes into 170 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 16457.1578
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
When dividing 180 by 19, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 16457.15789
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
The number 19 fits into 90 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 16457.157894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 16457.1578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 19, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 16457.15789473
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 16457.15789473 with a remainder of 1.3e-08.
